Interface: Graph3dTraceLink

The links.

Properties

Property	Type	Default value	Description
arrow?	Graph3dTraceLinkArrow	undefined	Arrowheads, as cones. Their tips stop at the node's surface, whatever its size.
color?	PerPointColor	undefined	Link color, or one per link. Default: a translucent gray that reads on the plot background, light or dark.
curve?	PerPointNumber	undefined	How far a link bows out, as a fraction of its length: 0 is straight. A link bows sideways: for someone who looks down the z axis, positive is to the left of its direction and negative to the right; a link that runs along z bows along y. One value, or one per link. Default: straight, except that the links between the same two nodes are fanned out so that each can be seen, two opposite links bowing apart. Range: -2 – 2
customdata?	DataColumn	undefined	Extra data per link for %{customdata} and events.
dash?	string	"solid"	Dash style of the links drawn as lines: 'solid', 'dot', 'dash', 'longdash', 'dashdot', 'longdashdot', or a dash list such as '5px,10px,2px'.
hoverinfo?	"all" | "none" | "skip"	"all"	Hover of the links: labels ('all'), events without labels ('none') or no hover and no events ('skip'). Default: the trace hoverinfo.
hovertemplate?	string	undefined	Template of the link hover labels: %{label}, %{value}, %{source.label}, %{target.label}, %{source.index}, %{target.index}, %{customdata}. <extra>…</extra> replaces the trace name.
label?	DataColumn	undefined	Link labels, shown in hover labels.
opacity?	number	1	Link opacity (multiplied by the trace opacity and the color alpha). Range: 0 – 1
render?	"auto" | "line" | "tube"	"auto"	'line': screen-space lines, link.width CSS px wide at every depth. 'tube': lit tubes link.width across, which are part of the scene like the spheres. 'auto': tubes when the widest link is 3 px or wider and the graph has at most 5,000 links, else lines.
source?	DataColumn	undefined	Source node index of every link. A link whose source or target is not a node is dropped.
target?	DataColumn	undefined	Target node index of every link. A link from a node to itself is drawn as a ring beside the node, on the side away from its neighbours.
value?	DataColumn	undefined	A positive number per link: its weight for the layouts (a stronger pull, a shorter link) and %{value} in hover labels. It sets the width only with link.widthby: 'value'. Missing or non-positive values count as 1.
width?	PerPointNumber	1	Link width in CSS px, or one per link: at every depth for lines; for tubes their diameter at the middle of the scene in its first view (see link.render). Ignored with link.widthby. Minimum: 0
widthby?	"none" | "value"	"none"	'value': widths from link.value, proportional to it, between the two widths of link.widthrange (the largest value gets the second).
widthrange?	readonly number[]	[1,8]	With link.widthby: 'value': the widths in CSS px of a link of value 0 and of the link with the largest value.
